Summary of Professor Herbert. H. Einstein Seminar on
“Making Decisions with DAT – Recent Extensions for Underground Cavern Developments”
1st and 2nd August 2013, NTU-JTC I3C, CEE, NTU

Professor Herbert H. Einstein, Professor in Civil Engineering at the Massachusetts Institute of Technology (MIT), USA and the author or co-author of more than 200 professional papers was invited by the NTU-JTC Industrial Infrastructure Innovation Center (I3C) to conduct a two-day seminar “Making Decisions with DAT – Recent Extensions for Underground Cavern Developments”, at the School of Civil and Environmental Engineering, Nanyang Technological University, on 1st and 2nd of August, 2013.

Seminar Day 1: Professor Einstein prepared two preliminary sessions for the participants to understand the “Decision Aids for Tunneling, DAT” system. In the first session “MIT Research in Rock Mechanics and Engineering”, Professor Einstein started with an overview of the recent research work conducted at MIT, focusing on rock fractures and related domains with in depth discussion on the geometrical and mechanical aspects of rock fractures. This was followed by an enlightening second session, “Engineering Geology and Tunneling: A Review of Empirical Tunnel Design”, where Professor Einstein reviewed the various existing empirical tunnel design methods. The participants benefited from the seminar especially when Professor Einstein pointed out the pitfalls of the various existing empirical tunnel design methods.

Seminar Day 2: “DAT – Decision Aids for Tunneling”, showcased the collaboration effort of the local government agencies with NTU and MIT. NTU demonstrated the successful trial of the application and modification of the Decision Aids for Tunneling (DAT) system in the risk assessment of local underground projects. The seminar was followed by Professor Einstein, the founder of the DAT, explaining the principles of the DAT in details. Professor Einstein explained the latest updated functions and the development of the resource management modules. In addition, Professor Einstein presented various DAT applications in different underground tunnel and cavern projects all over the world and highlighted the importance of DAT in evaluating the risk perspective in Singapore underground cavern construction. In the closing session, Professor Einstein introduced the latest work on DAT with a brief overview of event predictions using Bayesian networks and Artificial Neural Network (ANN) for estimating surface settlement during tunneling construction.
